IMPROVEMENT IN COPY-BOOKS.

Specification forming part of Letters Patent N0. 222,350, dated December9, 1879; application filed July 12, 1879.

To all whom it may concern:

Be it known that I, JONATHAN W. 0. GIL- MAN, of Maiden, in the "countyof Middlesex and Commonwealth of Massachusetts, have invented anImprovement in Writing and Drawing Books, 850., of which the followingis a specification.

This invention relates to a writing, drawing, or other exercise book,which is provided with one or more removable leaves orpages having oneor more tongues adapted to be inserted between and held by the portionof the leaves through which the binding-thread is passed and by the saidthread.

It further relates to the means for securing said leaf or page to thebook. I It is desirable, for obvious reasons, that scholars shouldpractice their writing, drawlng, or other exercises before transcribingthem upon the pages of the exercise-book, and

it has become the customof dealers in school-' books to furnish what isknown as practice fuse. The books having pages for practice bound in aretoo expensive for common use.

Reference -is made to the accompanying drawings in explaining the natureof my invention, in which Figure 1 represents a perspective of an openduplex writing-book with the practice-page a in position,the said pagebeing fastened to the book by the tongues or projections a, which areinserted between the leaves a a as shown, and are held by them and thebinding-thread c Figs. 2 and 3 illustrate the practice-page prepared forattachment to the writin g-book by having the tongues or extensions aformedon the margin thereof in such manner as not to contact with thebinding-thread when inserted into the book. Fig. 4. is a perspectiveillustrating a method of looking a practice-sheet to the book .by meansof the extensions (1. upon the tongue.

These extensions a must project sufficiently beyond the binding-threada. so that the thread is embraced by the recesses a so arranged upon theinner edge of the prac- I Lice-page as to permit the recesses B to comein line with that portion of the binding-thread a which passes throughthe leaves to the back A of the book.

It will thus be seen that my invention consists in a bound writing,drawing, or other exercise book provided with one or more detachablepages, which are secured therein in the manner indicated, and in asheet, leaf, or page of practice-paper provided with one or'more tonguesor extensions, which are adapted to be inserted between and held by theportion of the bound leaves of the book through which the binding-threadis passed and by the said thread.

The advantages of the invention consist in .the facilitywith which thepractice sheet, leaf,

or page can be attached to the writing or other book; in the firmnesswith which it is held; in the ease with which it can, be removed, and inthe economy and simplicityofthe construction.

Having thus fully described my invention,

I claim and desire to secure by LettersIfat-f ent of the United States-1 1. A writing, drawing, or other. exercise book provided with one ormore detachable.

leaves of practicepaper having the tongues a and recesses 13, and whichare fastened in said book by said tongues or projections on said leavesinserted between and held by the portion of the bound leaves of the bookthrough which the binding-thread passes and by said thread, allsubstantially as described.

2. A practice leaf, sheet, or page adapted to be fastened to a boundwriting, drawing, or other exercise book provided with one or moretongues or extensions, a, for insertion between the boundportions of theleaves of the book, i

and with the'recess or recesses B between the tongues, substantially asand for the purposes described.
